Diving systems and related equipment must be well designed and thoroughly tested to make them safe, reliable and compliant.

DNV GL has wide-ranging experience in the classification of diving systems. Having been involved with diving systems since the beginning of the offshore diving industry, our first full rule set was published in 1975 (Rules for the construction and classification of diving systems).

DNV GL remains the leading class society, offering experienced approval engineers and specially trained surveyors worldwide as well as maintaining contacts with the industry via interaction with operators, end users and regulators.
